Installation Notes and Tips

Compatible With 1997-2002 Cadillac Eldorado, rear; 1997-1999 Cadillac DeVille, rear; and 1997 Cadillac Seville, rear. This kit is for vehicles not equipped with Road Sensing Suspension. Verify the original mount style and suspension configuration before installation. The upper mount uses a stud design and the lower mount uses a loop/eyelet design.

AS-2177 is air adjustable and uses spring isolators and a lower mounting isolator. Mounting hardware is not listed as included, so confirm reuse or replacement needs during service. Because this application is tied to rear air leveling, inspect related air suspension components and electrical bypass requirements during diagnosis.
